This typically means that the Nova scheduler could not find a host on which to launch an instance. Take a look at the various nova logs (scheduler or compute) and you'll find more details of the failure there.

Everything was running perfectly fine. I did centos update. After that I'm getting this error "No valid host found". nova-services are running. All compute nodes are also connected with each other.
